Kate Middleton's wedding dress designer is a closely-guarded secret, but maid of honour Pippa Middleton doesn't seen as worried about keeping the designer of her dress under wraps.
Kate's sister and mother Carole were snapped kissing designer Alice Temperley goodbye after spending three hours at her London office.
The meeting has also fuelled speculation that Alice will be designing Kate's wedding dress, too.
While Pippa was probably meeting Alice about designing her own bridesmaid dress, Kate is known to be a fan of her work.
She wore a black and white dress by the designer for her first official engagement with William in December when they attended a charity carol concert in Norfolk.
A source told the Daily Mail: 'Kate loves Alice's collections, especially the simplicity of the designs.'
Alice is one of the designers who've been tipped as Kate's dress creator, along with Princess Diana's favourite Bruce Oldfield, and McQueen designer Sarah Burton.
Buckingham Palace said of Pippa's fitting with Alice: 'It was a private meeting between two individuals.'
Kate is understood to have commissioned two dresses for her big day on 29 April.
She will change from her Westminster Abbey gown into a second dress for the evening reception Prince Charles is hosting at Buckingham Palace.
A friend said: 'She is loving the fact no one knows who she will wear. Close friends don't know.'
But has Pippa given us the biggest hint yet?
